Jerry: Why don't you just find the stamped engine number at the front block on the drivers side, just below the head. We've been pointing you there for days now.

hi
yes you are correct. The power steering pump prevents me from seeing 1 of the 7 digits, which I assume is the first digit. The digits I can see are 207370. Also on the block I can read 6661 or 6667 which I have read tells the date the block was built. 6661 would be June 6, 1961, for example. When I know the series of numbers of the blocks for 1961 and 1967, hopefully I can see that 207370 fits into the series of numbers for one of those years. Thanks for your continued interest and support. Merry Christmas, Jerry

I'm not sure if you are still searching, but I don't think Mopar used a linear sequence for the A block casting numbers. I know a 1959 casting is 737929 and a 1961 is 2264230 and 2737929, but then a 1966 is 2532630. The stamped code is the way to go since a 1957 - 1961 block could have ended up in a 1961, and a 1962 - 1966 block could have ended up in a 1966 (1967 Canadian) depending on what the factory had lying around.

Jerry, several of us are wondering why you keep focusing on the casting numbers when the letter beside the engine size ie 318 tells what year the engine was used. The blocks and crankshaft flanges were changed in 62 so if your engine is bolted to a cast iron torqueflight it has to be 61 or older. So far, no one has made adapters to bolt the older engine to the newer trans.

58coupe - 2022-01-16 9:48 AM So far, no one has made adapters to bolt the older engine to the newer trans.

From my understanding, Wilcap makes an adapter kit to fit 1962+ TorqueFlites and bellhousings to 1956 - 1961 A-blocks. Similar kit as the 392 from my understanding, or at least the adapter plate since the bellhousing bolt pattern/alignment pins are the same.

Jerry, if you can see the back of the block, it's very easy to tell if it's an early or later A. The early's crankshaft sticks out about 2" from the block, whereas the later crankshaft is right off the block. Also, the early block has large ribbs cast into the back, whereas the later block doesn't.

My mistake, I meant to say newer engines to older trans. (automatic). There is a member here, Wayfairer, Qualityengineeredcomponents.com That is working on it, plus he makes adapters for the older engines to newer trans. at better prices than Wilcap as I am using one of his.

I got Jerry an answer that he was happy with in second thread that he started about his mystery 318.

From your recently posted photos, I see two bolt valve covers.
Jerry: According to Pg. 9-26 in the 1955-58 Parts book, the 57-58 Mopar P29 318 engine used a 3 bolt valve cover with PN 1827 401.
By 1959, they had changed to a two-bolt valve cover design, PNs 1859 432 (right) and 1945 506 (left)
For 1960, they stuck with the two-bolt valve cover design with the same 1859 432 (right) and 1945 506 (left) up to engine No. 65030, then they had
new PNs 2128 404 (right) and 2128 405 (left).
So, without seeing the actual engine number, the safe guess is that your 318 was NOT original to a 1958 Plymouth. It could be from a 1959 or 1960 or later (??)

I didn't know Gary made the aluminum TF to early A-block adapter, so thanks for that info. Seeing how he sorts making the 1962+ A318 block and crank work on an iron transmission will be interesting.

Valve covers are interchangeable on all 1956 - 1966 A-blocks, so they can't be trusted identifiers. 1966 heads are machined to accept the center bolt.

Thanks, I assumed (apparently incorrectly) that the heads with the 2 bolt valve covers would NOT be prepped for 3 bolt covers (drilling and tapping the boss on the head for the middle bolt). Live and learn.
